This is a disassembled but functional ROBOTIS TURTLEBOT3 Waffle Pi. It is a discontinued product. Thank you. The LDS-01 is a 2D laser scanner (LiDAR) that can detect 360 degrees. It collects point cloud data around the robot and is used for SLAM (Simultaneous Localization and Mapping). Based on a Hitachi-LG Data Storage LiDAR, it supports a USB interface with a ROBOTIS signal conversion board. It can be easily connected to a PC and supports ROS1 and ROS2.
